A 6 m long steel column of cross-sectional area  mm2  is loaded in tension with a force P=  N as shown.  Take the Modulus of Elasticity of steel to be 200,000MPa.  a) Assuming the beam does not deform plastically, how much will the column extend by under this load?  Provide your answer in units of mm to 2 decimal places.

A steel rod with a length of 2 meters and a cross-sectional area of 0.002 m² is stretched by a force of 800 N. What is the strain in the rod?

A square column of wood is 2.5 m long with pinned ends. Taking a factor of safety of2.5 in computing Euler critical load and also taking the allowable compressive stress as12 N/mm2, find the size of the cross-section, if the column has to safely support (i) 150KN (ii) 275 KN. Take E=1.3 X 104 N/mm2
